The website is easy to use, the message assistant is fast and useful to answer any questions, the price is decent with coupons. I got TRZ 60mg, and BAC water, the delivery arrived as promised, used for research and is as effective as Zepbound so far. I was gentle to let the BAC water enter slowly to the side of the vile and swirl the vile gently. Both at room temperature. After I placed the vial in the fridge away from light, same with BAC water. I am very happy with it. I scanned the QR code on the vial and it gave me access to the COA certificate.
